The two latest patients are both adults that live in Allegheny County, and were not vaccinated.

But health officials add that there have been no additional public exposures because the family was given quarantine orders.

The other four cases were first reported on May 2.

Three family members, including two children and one adult, are not county residents but are visiting from overseas. The two children are unvaccinated and the adult is reportedly vaccinated.
